摘　　要：分析了定量研究钢—混凝土组合梁的界面滑移对组合箱梁刚度和挠度影响的必要性,建立了考虑滑移效应的箱型钢—混凝土组合梁的变形模型,并提出了利用最小势能原理,推导组合梁变形微分方程的建议,可供结构设计人员参考。The influences of inter-surface slip of steel-concrete composite beam on rigidity and deflection of composite beam are quantitatively analyzed. Taken slip effect in considerations the deformation model of box-type steel-concrete composite beam is built, at the same time princi- ple to utilize the minimum potential energy is proposed. Suggestions are also proposed for derivation of deformation differential equation of composite beam, in order to provide references for designers.
